SEAL - PISTON (Komatsu KO34C-64-21360)

A worn piston seal can allow fluid bypass, reducing system pressure and causing sluggish operation. This aftermarket replacement part references Komatsu as the OE maker and cross-references part number KO34C-64-21360. The seal type is a piston seal, which creates a barrier between moving and stationary surfaces inside a cylinder. Its plain mechanical function is to contain pressurized fluid while permitting piston movement. A generic failure consequence is that a degraded seal leads to internal leakage, diminishing force output and cycle consistency. The item ships at approximately 0.01 pounds. Verify the serial number or application, then call (562) 693-7748.
